Calling it a driver is glorifying it a bit ;)

Whilst the DEC2000-t also has a TDA10045H for the frontend, everything gets 
passed to it down a USB cable, so I can only guess at what the chip itself 
might be after.  Also, the only bit implemented is tuning to a frequency, so 
it's rather skeletal right now.

If you do have a go at writing a generic TDA10045H frontend don't be afraid to 
completely disregard the stuff in the dec driver, because it's likely to be 
very very very specific to the dec driver.

I couldn't find any documentation on the TDA10045H's registers, so if you find 
any, please let me know.  It could possibly be useful for reverse-engineering 
the usb transmissions for the dec.

Cheers,
Alex
